f To all who'mit may con'ceh't'.' Y

Beit knowny that I, AUGUST T. NISWANGER,

a citizen ofthe United V`States,"residing at' Seattle, in tlh'e' county of King'and State of i' havey invented a new and user` `ful Improvement inPost-Hole-Drilling Machines, tion.

of this improvement `is to provide ay machine thatcan be manually actuatedlto ydrill post holes very quickly through arotary process.l

A1 further object resides inadaptability of Ithe drillingmechanism to swing to various positions onthe framefor boring operations. A stillfurther object resides in the adapt ability',y of" vthe 'machine -tofbe moved' :froml place` 4*to place Without having-to be dismantled, andfin theadjustabili-ty of the sup#Y the drilling' mecha" evel v'planef f porting legs to maintain nism in fa Further objects will appear`f1om`the fol-ylowing* sp.eeification,-y illustrated in theac- `out theapp'ended claims. nthe drawings,

machine.`

Referring more partifnilarly tothe draw; j ings, in which like reference numerals indi-Tr cate like parts, theI numeral llrepresents the frameV ofthe vmachine supportedy upon eXten- 'sion legs 2, and these 'legs are l'adapted4 to be extended 'to variousy adjustable positions by sety 'screws 3. Disposed intermediate tlhey upper and lower partsof the vframe 1` aref integrally connected gears 'a ysometimes known as"Si'am'ese gearsj.y and theselgears are disposed for j longitudinalv ,movement upon a rotatableshaft' vertically mounted 1ipon the frame 1. l

6 is a plate disposed upon theupper face of the frame 1 and this plateY is projected outwardly from the frame to one side thereof and has att-ached thereto a supporting stabilizer 7 adapted to make Contact with the ground and adjustable in length by means of a set screw 8.

of' which the following is a specifica` 1 a' through the Aouter'projection of the member` This invention relatesto improvements infflO-and plate 6,fand upon the lower end of post hole drillingV lmacliines,== and the obj ect any well known' manner;`

12 isa threaded'bar 'nou-nted for rotation Simfree omer.

thisthreaded 'bar is attached an auger 25 in f Disposed intermediate the plate 6 and the l when'the shaft 5. is rotated, the threaded bar 12 will berotatably actuated-to move up and k1down through its meshing contact With the threaded slots infthe plate 6 and member l0\` tlhrough which yit protru'des.

14 is a Ashaftr rotatably mounted through the side `of the frame 1 and' upon the end of Y'this shaft is ixedly secured a beveled pinion "15 intermediate the adjacent facesof the integrally connected gearsf with which it is n adapted'to alternately engage in meshing "I contact, and, upon the outer end '14 is 'provideda ixe'dly securedy pulley-'16 having'a handleJv "17v attached thereto transof tlhe shaft versely thereof upon its outer periphery.

18 is' a" lever pivotallyy attached to a l ,bracket 19 projecting downwardly from the frame 1, one end of the lever being formed into 'a yole 2O and adapted topivotally en gagetheopposite sides of the ihub of' the integrally connected gears t, and-f the ot'her slot vby afcompresslon spring 245 interposed betweentheflever 'handle 21 and .the handle 'portion'. of ble pin 22 whereby theactuation of the lever 218 will shift the integrally' connected gears 4 longitudinally upon the shaft 5 to engage alternately the beveled pinion 15, theppin 22 being herein adapted to hold the lever l18 in lcontact'Withthe lframev and thus retain the vintegrally connectedl gears 4' endY of the lever beingformedwith ya handle 21 and.having'pivotally'y attached thereto a pin 22 for engaging aslot 23 provided inthe lowerppart of the upper frame 1, and this pin is yieldingly actuated toengage this after each boring operation, 'provision has been made for shifting the drilling mechanism to assume various positions around the sides of the frame Without having to shift the position of the frame. This function is obtained by disengaging from frictional contact the cam pin 26 with the sides of the slotted channel 27 provided around the outer periphery of the plate 6, kthereby permitting the superimposed mechanism upon the frame 1 to be shifted to various positions confined to the radius of the circular channel from the shaft 5,which constitutes the pivotal point of contact. n

28 is a pivotally mounted truck frame attached to brackets 29 extended down-v wardly from the lower frame 1 of the machine on one side thereof, and upon the ends of this truck frame are provided rotatably mounted wheels 30, the balance of the truck frame at the pivotal point being such that the wheels w1ll be automatically elevated clear of the ground when pressure has been ing a removed from the elongated ends thereof. It is obvious that provision of these wheels Will provide means for easily moving the machlne over the ground without having to disassemble and reassemble the machine at the various places of operation.

It is to be understood that many mechanical changes can be made in the details of construction Within the scope of the following claims.

What I claim as new, and desire to protect by Letters Patent, is

l. A post hole drilling machine comprising a frame structure, a shaft rotatably mounted upon'said frame structure, reversible means for rotating said shaft, means superimposed upon said frame and supported from the ground at one side thereof, a threaded bar, a pinion thereon cooperating with said means for actuating said bar upwardly and downwardly, an auger attached-to the lower end of said bar and a gear wheel fxedly secured to said shaft and adapted to actuate said pinion, whereb f said auger can be caused to enetrate t e ground and be removed tierefrom.

2. A osth-ole drilling machine comprisrame structure, a shaft rotatably mountedvupon said frame structure, integrally connected gears keyed for` longitudinal movement upon said shaft, a beveled pinion adapted .to mesh alternately,7 with said integrally connected gears, a lever for actuating said integrally connected ears to move longitudinally upon said s aft to establish forward and reverse speed, threaded means superimposed upon said frame and supported from the ground at one side` thereof, a threaded bar received therein and an auger therefor, a gear wheel keyed for longitudinal movement upon said threaded bar, a gear fixedly secured to said shaft in meshing contact with said gear wheel eled pinion adapted to be manually actuated, integrally connected gears keyed for 4longitudinal movement upon said shaft, a

lever for actuating said gears to alternately' engage said beveled pi'nion to establish forward and reverse speeds, threaded means superimposed upon said frame and supported from the ground at one side thereof, a threaded bar received therein and an auger therefor carried by said means, a gear wheel keyed for longitudinal movement upon said threaded bar, a gear xedly secured to said shaft in meshing contact with .said gear wheel, whereby said auger can be caused to penetrate the ground and be removed therefrom, and means for shifting the drilling mechanism superimposed upon said frame around the sides thereof ing a frame structure having legs adjustable in length with respect thereto, a shaft rotatably mounted upon said frame struc-l ture, a beveled pinion adapted to be manually actuated, integrally connected gears 4keyed for longitudinal movement upon said shaft, a lever for actuating said ears to alternately engage said beveled pinion to establish forward and reverse speeds, threaded means superimposed upon said frame and supported from the ground at one side thereof, a threaded bar received therein and 'upon said frame around the sides thereof.
